ESXi 6.0 Windows Server 2016 OpenGL 2.0

I'm looking for a bit of advice on the possibilities of supporting OpenGL 2.0 on a Windows Server 2016 VM running on an ESXi host.

Currently the VM reports it is capable of OpenGL 1.1, but I need 2.0 support for a particular application. It's not doing 3D, but the interface is rendered in OpenGL 2.0, so support is required.

I've tried various things, like switching the Client OS to Windows 10 in settings to allow me to enable 3D video, and changing the driver to WDDM, but cannot seem to get anything to work. The host machines are HP Proliant servers, with built in graphics, so I don't know if this is the problem.

I'm really looking for some guidance on what I'd need to do to make this work, even if the answer is new hardware.

Thanks

Dan
